Stevie’s Car Thefts (After “No. 1”): Text messages with car locations. Deliver to garage in Bohan. $10k–$30k per car. ~$500k total. Repeatable? No, once per save.
Assassinations (The Fixer / U.L. Paper): Pay $5k–$10k per hit. Fast.
Drug Wars (TLAD) / Gang Wars (TBoGT): Repeatable. Good cash + Weapons/Armour.
Glitches (Patched): “Swing Set Glitch” (Launch car → sell), “Bank Truck” respawn exploits. Fixed in Title Updates. Attempting on updated game = Waste of time / Ban risk (MCC/Online).
Mods / Trainers (PC Only)
Simple Native Trainer → Player > Money > Add $1,000,000.
Script Hook V + Custom Scripts.
Recommendation: Play the story. Money becomes irrelevant after “A Dish Served Cold” (final mission). You get $250k+ anyway.
